Definitions

  • the invention relates to a lifting device for the cabin of a passenger transfer vehicle at an airport.
  • Such vehicles which enable passengers to be carried up to the level of the entry door of an aircraft have already been proposed, but they involve a lifting device including a jack which, in view of the need to raise the cabin by more than three meters, must extend higher than the cabin and thus make the vehicle inconveniently high.
  • An object of the invention is therefore to replace the known jack device by a lifting device which enables the lifting device to be accommodated beneath the top of the cabin.
  • a lifting device especially for the cabin of a passenger transfer vehicle as used in airports, comprises an upwardly-movable pusher chain arranged to run in a guide sheath and movable upwardly and downwardly by a chain-driving motor, the sheath being slidable within a second sheath, surrounding it and integral with the base of the device, and the chain comprising a first section having central and lateral rollers by which it is guided in the first sheath and a second section having lateral rollers guiding it in the second sheath, the first sheath abutting against the spindle interconnecting the two sections of the chain.
  • FIG. 1 is a schematic view of the lifting device according to the invention
  • FIG. 2 is a detailed sectional view of the device on a horizontal line as viewed in FIG. 1 and to a larger scale;
  • FIG. 3 is a detailed side view of the lower part of the device looking from the right as viewed in FIG. 1 and to a larger scale;
  • FIG. 4 is a lower part of the device shown in FIG. 1 to a larger scale
  • FIG. 5 is a schematic view of a common drive for two devices as shown in FIGS. 1 to 4.
  • the lifting device is mounted on a vehicle carrying a cabin 4 for transferring passengers at an airport to the level of the entry door of an aircraft.
  • the lifting device shown in FIGS. 1 to 4 comprises a chain 1 driven by a sprocket wheel 2.
  • the upper end of an upright portion of the chain 1 bears against an abutment 3 integral with the cabin 4.
  • the chain is arranged within a telescopic mast comprising three sections 5, 5a, 5b, the section 5 being fixed to the cabin 4 and the section 5b being integral with the chassis 6 of the vehicle.
  • the intermediate section 5a will surround the section 5 within the cabin 4 and the intermediate section 5a will be retracted within the lowest section 5b and thus the bottom of the cabin 4 will be close to the chassis 6 of the vehicle.
  • the chain 1 is guided by two telescopic sheaths, namely a first sheath 7 constructed from a U-section member having a rail 8 for defining a track for central rollers 9 of an upper section 1a of the chain and two tracks 10 for lateral rollers 11 of the upper section of chain.
  • This first sheath 7 is surrounded by a second sheath 12 carrying guide rollers 13 engaging in a channel 14 on the first sheath and channels 15 in which run rollers 16, mounted laterally on the sheath 7, and lateral rollers 17 on a lower section 1b of the chain 1 also having central rollers 9.
  • the upper secton 1a of the chain has a length substantially equal to that of the sheath 7 which acts as a guide for this section.
  • the lower section 1b of the chain has the lateral rollers 17 thereof, wider apart than the rollers 11 of the upper section and guided within the sheath 12.
  • the two sections 1a and 1b are connected end-to-end by a link having a spindle provided with sleeves 18 which form driving dogs for the moving sheath 7 within the sheath 12.
  • the sprocket wheel 2 is formed by a double toothed pinion, the downward thrust of the chain on the wheel 2 being absorbed by a rail 19 along which travel the central rollers 9 of the spindles of the links of the chain.
  • the central rollers 9 each have a shoulder-piece 20 (see FIG. 4) which prevent the chain from curving in the opposite direction from that which it follows round the pinions of the sprocket 2.
  • the chains are driven in the downward direction, the lower section 1b of each chain flexing around the toothed pinions of the driving sprocket 2, as indicated in FIG. 4.
  • the sheath 7 will be retracted within the sheath 12 and the sections 5, 5a, 5b of the mast will be telescoped one within another.
